Martin, Actually, for my part the 3 SO-239 connectors offer the greatest flexibility. If a user uses open wire feeders, he likely already has a balun connected to those feeders. To move that balun inside the tuner makes no sense to me. In fact, I have an MFJ 962D tuner that I removed the internal balun just so I could connect a 3rd SO-239 connector. The baluns live at the center of my antennas or at the end of the ladder-line (which is not in the shack).
